“Sales sells the first car and service sells the rest” (car dealership adage)

“Sales sells the first car and service sells the rest” is an old adage among car dealers. It’s not known who said it first.
   
“We believe sales sells your first car, but service sell the next” was printed in the South Bend (IN) Tribune on October 13, 1983. “Sales sells the first car, and service sells it thereafter” was printed in the Sun Sentinel (Fort Lauderdale, FL) on April 7, 1985. “Most sales managers now realize that sales sells the first car and service sells the rest” was printed in the Automotive Executive in 1988.

Service-to-sales can be a gold mine

Selling out of the service lane begins when a dealership’s salespeople introduce new-vehicle buyers to the service department at the point of sale, says Todd Farrell, president of Benchmark X Inc., a sales consultancy in Sioux Falls, S.D.
 
That handoff lets buyers know that the dealership’s service department can take care of them, and also repair vehicles that weren’t purchased there, he says. It is a “100 percent profitable situation,” Farrell says. “Sales sells the first car, service sells all the rest.”
